Subject[PATCH v6 0/9] PCI: mediatek: fixup find_port, enable_msi and add pm, module support
Date
From: Honghui Zhang <honghui.zhang@mediatek.com>

This patchset includes misc patchs:

The patch 1 fixup the mtk_pcie_find_port logic which will cause system
could not touch the EP's configuration space that connected to PCIe slot 1.

The patch 2 fixup the class type for MT7622.
The patch 6 fixup the enable msi logic, the operation to enable msi
should be after system clock is enabled. Call mtk_pcie_enable_msi in
mtk_pcie_startup_port_v2 since the clock was all enabled at that time.

The patch 7 was rebased and refactor of the v4 patch[1], changes are:
-Add PM support for MT7622.
-Using mtk_pcie_enable_port to re-establish the link when resumed.
-Rebased on this patchset.

The patch 9 add loadable kernel module support.

[1] https://patchwork.kernel.org/patch/10479079

Change since v5:
- A bit improvement of mtk_pcie_find_port suggest by Lorenzo.
- Add fixup tags of fix enable MSI logic in patch 6.
- Add Acked-by tags from Ryder.

Change since v4:
- Add patch 2 to fixup class type for MT7622.
- Add patch 3 to remove the redundant dev->pm_domain check
- Add patch 4 to covert to use pci_host_probe
- Add patch 5 to re-arrange the function define, this is a prepare patch for
fixup the enable_msi logic, no functional changed have been made by this one.
- Add patch 8 to save the GIC IRQ in mtk_pcie_port as a prepare patch for tear
down the irq when remove the kernel module.
- Re-arrange the find_port flow suggest by Lorenzo to make the code parse easier
for the patch 1.
- Remove the .pm_support in mtk_pcie_soc in patch 7 since if system pm was not
supported, then those pm callbacks will never be executed for MT7622. So the
.pm_support is not needed.

Change since v3:
- Remove pm_runtime_XXX ops in suspend and resume callbacks in the third patch.
- Rebase to 4.19-rc1.

Change since v2:
- Fix the list_for_each_entry_safe parameter error.
- Add Ryder's Acked-by flag.

Change since v1:
- A bit of code refact of the first patch suggested by Andy Shevchenko, and
commit message updated.
- Using __maybe_unused.
- Remove the redundant list_empty check of the fourth patch.
